Inattentional blindness

Inattentional Blindness is the event in which an individual fails to recognize an unexpected stimulus that is in plain sight. The term inattentional blindness was coined by Arien Mack and Irvin Rock in 1992 and was used as the title of Mack and Rock's book published by MIT press in 1998. Aquí, they describe the discovery of Inattentional Blindness and include a collection of procedures used in exemplifying the phenomenon.[1] Research on inattentional blindness, also sometimes referred to as perceptual blindness, suggests that this phenomenon can occur in all individuals, independent of cognitive deficits. It is simply impossible for one to attend to all the visual stimuli in a visual field, and as a result, a temporary "blindness" effect can take place. Es decir, individuals fail to see objects or stimuli that are unexpected and quite often salient. The following criteria are required to classify an event as an inattentional blindness episode: 1) the observer must fail to notice a visual object or event, 2) the object or event must be fully visible, 3) observers must be able to readily identify the object if they are consciously perceiving it,[1] y 4) the event must be unexpected and the failure to see the object or event must be due to the engagement of attention on other aspects of the visual scene and not due to aspects the visual stimulus itself.[1] Individuals who experience inattentional blindness are usually unaware of this effect, which can play a subsequent role on behavior. Inattentional blindness is related to but distinct from other failures of visual awareness such as change blindness, repetition blindness, visual masking, and attentional blink. The key aspect of inattentional blindess which makes it distinct from other failures in awareness rests on the fact that the undetected stimulus is unexpected.[2] It is the unexpected nature of said stimulus that differentiates inattentional blindness from failures of awareness such as attentional failures like the aforementioned attentional blink. It is critical to acknowledge that occurrences of inattentional blindness are attributed to the failure to consciously attend to an item in the visual field as opposed the absence of cognitive processing. Findings such as inattentional blindness - the failure to notice a fully visible but unexpected object because attention was engaged on another task, evento, or object - has changed views on how the brain stores and integrates visual information, and has led to further questioning and investigation of the brain and importantly of cognitive processes.

Más específicamente, there is disagreement in the literature about exactly how much processing of a visual scene is completed before selection dictates which stimuli will be consciously perceived, and which will not (es decir. Inattentional Blindness). There exists two basic schools of thought on the issue - those who believe selection is done early in the perceptual process, and those who believe it is done only after significant processing.[3] Early selection theorists propose that perception of stimuli is a limited process requiring selection to proceed. This suggests that the decision to attend to specific stimuli occurs early in processing, soon after the rudimentary study of physical features; only those selected stimuli are then fully processed. Por otro lado, proponents of late selection theories argue that perception is an unlimited operation, and all stimuli in a visual scene are processed simultaneously. En este caso, selection of relevant information is done after full processing of all stimuli.[4] While early research on the topic was heavily focused on early selection, research since the late 1970s has shifted mainly to the late selection theories. This change resulted primarily from a shift in paradigms used to study inattentional blindness which revealed new aspects of the phenomenon.[5] Hoy, late selection theories are generally accepted, and continue to be the focus of the majority of research concerning inattentional blindness. Evidence for Late Selection A significant body of research has been gathered in support of late selection in the perception of visual stimuli. One of the popular ways of investigating late selection is to assess the priming properties (es decir. influencing subsequent acts[6]) of unattended stimuli. Often used to demonstrate such effects is the stem completion task. While there exist a few variations, these studies generally consist of showing participants the first few letters of words, and asking them to complete the string of letters to form an English word.[6] It has been demonstrated that observers are significantly more likely to complete word fragments with the unattended stimuli presented in a trial than with another similar word.[7] This effect holds when stimuli are not words, but instead objects. When photos of objects are shown too quickly for participants to identify, subsequent presentation of those items lead to significantly faster identification in comparison to novel objects.[6] An interesting study by Mack and Rock has also revealed that showing a word stimulus differing from the participant's name by one letter did not generally call conscious attention. By simply changing a character, transforming the presented word into the observer's first name, the now highly meaningful stimulus is significantly more likely to be attended to. This suggests that the stimuli are being extensively processed, at least enough to analyze their meaning. These results point to the fact that attentional selection may be determined late in processing.[7] The evidence outlined above suggests that even when stimuli are not processed to the level of conscious attention, they are nonetheless perceptually and cognitively processed, and can indeed exert effects on subsequent behavior.[8] Evidence for Early Selection While the evidence supporting late selection hypotheses is significant and has been consistently reproduced, there also exists a body of research suggesting that unattended stimuli in fact may not receive significant processing. Por ejemplo, in an fMRI study by Rees and colleagues, brain activity was recorded while participants completed a perceptual task. Here they examined the neural processing of meaningful (words) and meaningless (consonant string) stimuli both when attended to, and when these same items were unattended. While no difference in activation patterns were found between the groups when the stimuli were unattended, differences in neural processing were observed for meaningful versus meaningless stimuli to which participants overtly attended. This pattern of results suggests that ignored stimuli are not processed to the level of meaning, es decir. less extensively than attended stimuli.[9] Participants do not seem to be detecting meaning in stimuli to which they are not consciously attending. Theories of Inattentional Blindness Perceptual Load This particular hypothesis bridges the gap between the early and late selection theories. Authors integrate the viewpoint of early selection stating that perception is a limited process (es decir. cognitive resources are limited), and that of the late selection theories assuming perception as an automatic process.[4] This view proposes that the level of processing which occurs for any one stimulus is dependent on the current perceptual load. Es decir, if the current task is attentionally demanding and its processing exhausts all the available resources, little remains available to process other non-target stimuli in the visual field. Alternativamente, if processing requires a small amount of attentional resources, perceptual load is low and attention is inescapably directed to the non-target stimuli.[3] The effects of perceptual load on the occurrence of inattentional blindness is elegantly demonstrated in a study by Fougnie and Marois. Aquí, participants were asked to complete a memory task involving either the simple maintenance of verbal stimuli, or the rearrangement of this material, a more cognitively demanding exercise. While subjects were completing the assigned task, an unexpected visual stimulus was presented. Results revealed that unexpected stimuli were more likely to be missed during manipulation of information than in the more simple rehearsal task.[10] In a similar type of study, fMRI recordings were done while subjects took part in either low-demand or high-demand subtraction tasks. While performing these exercises, novel visual distractors were presented. When task demands were low and used a smaller portion of the finite resources, distractors captured attention and sparked visual analysis as shown by brain activation in the primary visual cortex. These results, sin embargo, did not hold when perceptual load was high; en esta condición, distractors were significantly less often attended to and processed.[3] Así, higher perceptual load, and therefore more significant use of attentional resources, appears to increase the likelihood of inattentional blindness episodes. Inattentional Amnesia The theory of inattentional amnesia provides an interesting alternative in the explanation of inattentional blindness. It suggests that this phenomenon does not stem from failures in capture of attention or in actual perception of stimuli, but instead from a failure in memory. The unnoticed stimuli in a visual scene are attended to and consciously perceived, but are rapidly forgotten rendering them impossible to report.[11] En esencia, inattentional amnesia refers to the failure in creating a lasting explicit memory; by the time a subject is asked to recall seeing an item, their memory for the stimulus has vanished.[12] While it is difficult to tease apart a failure in perception from one in memory, some research has attempted to shed light on the issue. In a classic study of inattentional blindness, a woman carrying an umbrella through a scene goes unnoticed. Despite stopping the video while she is walking through and immediately asking participants to identify which of two people they have seen - leaving as little delay as possible between presentation and report - observers very often fail to correctly identify the woman with the umbrella. No differences in performance were identified whether the video was stopped immediately after the unexpected event or moments later. These findings would seem to oppose the idea of inattentional amnesia, however advocates of the theory could always contend that the memory test simply came too late and that the memory had already been lost.[13] Expectation The very phenomenon of Inattentional blindness is defined by a lack of expectation for the unattended stimulus. Some researchers believe that it is not inattention that produces blindness, but in fact the aforementioned lack of expectation for the stimuli.[8] Proponents of this ideology often state that classic methods for testing inattentional blindness are not manipulating attention per se, but instead the expectation for the presentation of a visual item.[14] Studies investigating the effect of expectation on episodes of inattentional blindness have shown that once observers are made aware of the importance of the to be presented stimuli, for example stating that one will later be tested on it, the phenomenon essentially disappears.[7] While admitting to possible ambiguities in methodology, Mack, one of the foremost researchers in the field, holds strongly that inattentional blindness stems predominantly from a failure of attentional capture. He points out that if expectation does not mediate instances of very closely linked phenomena such as attentional blink and change blindness (whereby participants have difficulty identifying the changing object even when they are explicitly told to look for it), it is unlikely that inattentional blindness can be explained solely by a lack of expectation for stimulus presentation.[8] Classic Experiments Demonstrating Inattentional Blindness Invisible Gorilla Test The Invisible Gorilla Test is one of the most widely known experiments pertaining to inattentional blindness. It was done by Daniel Simmons from the University of Illinois at Urbana–Champaign and Christopher Chabris from Harvard University. Their study was a revised version of earlier studies conducted by Ulric Neisser and Becklen in 1975. It consists of asking participants to look at a video of two teams, one black and one white, with three people on each. The participants are asked to count how many times a basketball is passed between members of the white team. While this is happening, a person dressed in a gorilla costume walks and stands in front of the camera, thumps its chest, then walks off camera. It is on screen for about 9 sobras. After watching the video, the participants are asked if they noticed anything out of the ordinary, and about half of them were so focused on counting, also known as selective attention, that they did not notice other stimulus in their eyesight, the gorilla. There are also other versions of this experiment, in which a woman walks through the scene carrying an umbrella, or in which the participants are asked to only count either aerial passes or only bounce passes.[15] In a subsequent and similar study by Daniel Memmert, the gorilla video was used but in addition, the eye movements and fixations of the participants were recorded and analyzed. It was found that the participants who failed to perceive the gorilla still spent about 25 frames or a total of one second fixated on it.[16] This classic study is a clear example of how people can fail to perceive a stimulus that is fully visible when their attention is focused on a different task, and as shown in the following example, inattentional blindness is applicable to real-life situations as well. Perception and Inattentional Blindness-A Real-world Experiment In 1995, Officer Kenny Conley was chasing a shooting suspect. An undercover officer was in the same vicinity and was mistakenly taken down by other officers while Conely ran by and failed to notice. A jury later convicted Officer Conley believing he had seen the fight, yet he stood by his word that he had, De hecho, not seen it. Christopher Chabirs, Adam Weinberger, Matthew Fontain and Daniel J. Simons took it upon themselves to see if this scenario was possible. They designed an experiment in which participants were asked to run about 30 feet behind Officer Conley himself, and count how times he touched his head. A fight was staged to appear about 8 meters off the path, and was visible for approximately 15 sobras. The procedure in its entirety lasted about 2 minutes and 45 sobras, and participants were then asked to report the number of times they had seen Officer Conley touch his head with either hand (medium load), both hands (high load), or were not instructed to count at all (low load). After the run, participants were asked 3 questions: 1) If they had noticed the fight; 2) if they had noticed a juggler, y 3) if they had noticed someone dribbling a basketball. Preguntas 2) y 3) were control questions, and no one falsely reported these as true. Participants were significantly more likely to notice the fight when the experiment was done during the day as opposed to in the dark. Adicionalmente, sightings of the fight were most likely to be reported in the low load condition (72%) than in either the medium load (56%), or high load conditions (42%).[17] These results exemplify a real world occurrence of inattentional blindness, and provide evidence that officer Conley could indeed have missed the fight because his attention was focused elsewhere. Además, these results add to the body of knowledge suggesting that as perceptual load increases, less resources remain to process items not explicitly focused on, and in turn episodes of inattentional blindness become more frequent. Limitations of Perception or Memory? Arien Mack and Irvin Rock’s findings on inattentional blindness is summarized in their 1988 book which comes to the generalized conclusion that no conscious perception can occur without attention.[7] Evidence through research on inattentional blindness contemplates that it may be possible that inattentional blindness reflects a problem with memory rather than with perception.[7] It is argued that at least some instances of inattentional blindness are better characterized as memory failures then perceptual failures. The extent to which unattended stimuli fail to engage perceptual processing is an empirical question that the combination of inattentional blindness and other various measures of processing can be used to address.[1] The theory behind inattentional blindness research suggests that we consciously experience only those objects and events to which we directly attend.[7] That means that the vast majority of information in our field of vision goes unnoticed. Thus if we miss the target stimulus in an experiment, but are later told about the existence of the stimulus, this sufficient awareness allows participants to report and recall the stimulus now that attention has been allocated to it.[1] Mack and Rock, and their colleagues discovered a striking array of visual events to which people are inattentionally blind.[7] However the debate arises whether this inattentional blindness was due to memory or perceptual processing limitations. Mack and Rock note that explanations for inattentional blindness can reflect a basic failure of perceptual processes to be engaged by unattended stimuli. Or that it may reflect a failure of memorial processes to encode information about unattended stimuli. It is important to note that the memory failure does not have to do with forgetting something that has been encoded by losing access to the memory of the stimulus from time of presentation to time of retrieval, rather that the failure is attributed to information not being encoded when the stimulus was present.[7] It seems that inattentional blindness can be explained by both memory and perceptual failures because in experimental research participants may fail to report what was on display due to failures in encoded information (memoria) or a failure in perceptually processed information (percepción).[7] Neuropsychological analogies of Inattentional Blindness There are similarities in the types of unconscious processing apparent in inattentional blindness and in neuropsychological syndromes such as visual neglect and extinction. The analogy between these phenomenon’s seems to generate more questions as well as answers. These answers are fundamental for our understanding of the relationship between attention, stimulus coding and behavior. Visual neglect Research has shown that some aspects of the syndrome of unilateral visual neglect appear to be similar to normal subjects in a state of inattentional blindness. In neglect, patients with lesions to the parietal cortex fail to respond to and report stimuli presented on the side of space contralateral to damage. Archivo:Parietal lobe animation small.gif Animation. Parietal lobe (rojo) of left cerebral hemisphere. [8][18] Es decir, they appear to be functionally blind to a range of stimuli. Since such lesions do not result in any sensory deficits, shortcomings have been explained in terms of a lack of attentional processing, for which the parietal cortex plays a large role.[19] These phenomena draw strong parallels to one another, as in both cases stimuli are perceptible but unreported when unattended. Extinction In the phenomenon of extinction, patients can report the presence of a single stimulus presented on the affected side, but then fail to detect it when a second stimulus is presented simultaneously on the 'good' (ipsilateral) side.[20] Here the stimulus on the affected side seems to lose under conditions of attentional competition from stimuli in the ipsilesional field.[20] The consequence of this competition is that the extinguished items may not be detected. Similar to studies of inattentional blindness, there is evidence of processing taking place in the neglected field. Por ejemplo, there can be semantic priming from a stimulus presented in the neglected field, which affects responses to stimuli subsequently presented on the unimpaired side.[21] Apparently in both neglect and inattentional blindness, there is some level processing of stimuli even when they are unattended.[21] However one major difference between neuropsychological symptoms such as neglect and extinction, and inattentional blindness concerns the role of expectation.[21] In inattentional blindness, subjects do not expect the unreported stimulus. En contraste, in neglect and extinction, patients may expect a stimulus to be presented on the affected side but still fail to report it when another it may be that expectation affects reportability but not the implicit processing of stimuli.[21] Further explanations of the phenomenon of inattentional blindness include inattentional amnesia, inattentional agnosia and change blindness. Inattentional Agnosia An explanation for this phenomenon is that observers see the critical object in their visual field but fail to process it extensively enough to retain it . Individuals experience Inattentional Agnosia after having seen the target stimuli but not consciously being able to identify what the stimuli is. It is possible that observers are not even able to identify that the stimuli they are seeing are coherent objects.[22] Thus observers perceive some representation of the stimuli but are actually unaware of what that stimulus is. It is because the stimulus is not encoded as a specific thing, that it later is not remembered. Individuals fail to report what the stimuli is after it has been removed. Sin embargo, despite a lack in ability to fully process the stimuli, experiments have shown a priming effect of the critical stimuli. This priming effect indicates that the stimuli must have been processed to some degree, this occurs even if observers are unable to report what the stimuli is.[23] Change Blindness Inattentional blindness is the failure to see a stimulus, such as an object that is present in a visual field. Sin embargo, Change Blindness is the failure to notice something different about a visual display. Change blindness is directly related to memory, individuals who experience the effects of change blindness fail to notice something different about a visual display from one moment to the next.[2] In experiments that test for this phenomenon participants are shown an image that is then followed by another duplicate image that has had a single change made to it. Participants are asked to compare and contrast the two images and identify what the change is. In inattentional blindness experiments, participants fail to identify some stimulus in a single display, a phenomenon that doesn’t rely on memory the way change blindness does.[2] Inattentional blindness refers to an inability to identify an object all together where as change blindness is a failure to compare a new image or display to one that was previously stored in memory.[2] Additional Factors Exhibiting Effects on Inattentional Blindness Age and Expertise In 2006, Daniel Memmert conducted a series of studies in which he tested the how age and expertise of participants affect inattentional blindness. Using the gorilla video, he tested 6 different groups of participants. There were 2 groups of children (average age=7) half with no experience in basketball, and the other half with 2 years experience; 2 groups of juniors (average age=13) half with no experience in basketball, and the other half with 5 years of experience; y 2 groups of adults (average age = 24) half with no experience in basketball, the other half with over 12 years of experience. He then instructed all the groups to keep track of how many passes the people on the black team made. Overall, the children with or without any basketball experience failed to perceive the gorilla more than the juniors or the adults. There were no significant difference between the inexperienced junior and adult groups, or between the experienced junior and adult groups.[16] This pattern of results suggests that until the approximate age of 13, presumably because certain aspects of cognition are still under development, inattentional blindness occurrences are more frequent, but become consistent throughout the remainder of the life span. Adicionalmente, the juniors with basketball experience noticed the gorilla significantly more than the juniors with no basketball experience; and the group of experienced adults noticed the gorilla significantly more than the non-experienced adults. This suggests that if one has had much experience with the stimuli in a visual field, they are more likely to consciously perceive the unexpected object. Similarity Between Stimuli A series of studies conducted to test how similarity can influence the perception of a present stimulus. En el estudio, they asked participants to fixate on a central point on a computer screen and count how many times either white or black letters bounced off the edges of the screen. El primero 2 trials did not contain an unexpected event, but the third trial was the critical trial in which a cross that had the same dimensions as the letters and varied in colour (white/light gray/dark gray/black) moved from the right side of the screen to the left side and passed through the central point. The results revealed the following: during the critical event, the more similar the colour of the cross was to the colour of the attended letters, the more likely the participants were to perceive it, and the less similar the colour of the cross was to the attended colour decreased the likelihood of the cross being noticed. For the participants attending to the black letters, 94% perceived the black cross; 44% perceived the dark gray cross; 12% perceived the light gray cross, y sólo 6% perceived the white cross. Semejantemente, if the participant was attending to the white letters, they were more likely to notice the cross it was white (94%) than if it was light gray (75%), dark gray (56%), or black (0%).[24] This study demonstrates that the more similar an unexpected object is to the attended object, the more likely it is to be perceived, thus reducing the chance of inattentional blindness. Benefits of Inattentional Blindness William James addressed the benefits of attention by saying, “Only those items which I notice shape my mind – without selective interest, experience is utter chaos”.[25] Humans have a limited mental capacity that is incapable of attending to all the sights, sounds and other inputs that rush the senses every moment. Inattentional blindness is beneficial in the sense that it is a mechanism that has evolved with attention to help filter out irrelevant input, allowing only important information to reach consciousness.[25] Several researchers, notably James J. Gibson, have argued that, even before the retina, perception begins in the ecology, which has turned perceptual processes into informational relationships in the environment through evolution.[26] This allows humans to focus our limited mental resources more efficiently in our environment. Por ejemplo, New et al. maintain that survival required monitoring animals, both human and non-human, to become part of the evolutionary adaptiveness of the human species. They found that when participants were shown an image with a rapidly altering scene where the scene change included an animate or inanimate object that the participants were significantly better at identifying humans and animals. New et al. argue that better performance in detecting animals and humans is not a factor of acquired expertise, rather it is an evolved survival mechanism in human perception.[26] Broader Implications Although the bulk of inattentional blindness research has been conducted in laboratory studies, the phenomenon occurs in a variety of everyday contexts. Depending upon the context, the occurrence of inattentional blindness could range from embarrassing and/or humorous to potentially devastating. Inattentional Blindness and Safety Several recent studies of explicit attention capture have found that when observers are focused on some other object or event, they often experience inattentional blindness.[27] This finding has potentially tragic implications for distracted driving. If a person’s attention is focused elsewhere while driving, carrying on a conversation or text messaging, por ejemplo, they could fail to notice salient and distinctive objects, such as a stop sign, which could lead to serious injury and possibly even death. There have also been heinous incidents attributed to inattentional blindness behind the wheel. Por ejemplo, a Pennsylvania highway crew accidentally paved over a dead dear that was on the road. When questioned regarding their actions, the workers claimed to have never seen the dead deer.[28] Many policies are being implemented around the world to decrease the competition for explicit attention capture while operating a vehicle. Por ejemplo, there are legislative efforts in many countries aimed at banning or restricting the use of cell phones while driving. Research has shown that the use of both hands-free and hand-held cellular devices while driving results in the failure of attention to explicitly capture other salient and distinctive objects, leading to significantly delayed reaction times, as well as inattentional blindness.[29] Alarmingly, a study published in 1997, based on accident data in Toronto, found the risk involved in driving while using a cell phone to be similar to that of driving drunk. En ambos casos, the risk of a collision was three to six times higher compared to a sober driver not using a cell phone.[30] Además, Strayer et al. (2003) found that when controlling for driving difficulty and time on task, cell-phone drivers exhibited greater impairment than intoxicated drivers, using a high-fidelity driving simulator.[31] Inattentional blindness is also prevalent in aviation. The development of Heads-up display (HUD) for pilots, which project information onto the windshield or onto a helmet-mounted display, has enabled pilots to keep their eyes on the windshield, but simulator studies have found that HUD may cause runway incursion accidents, where one plane collides with another on the runway.[25] This finding is particularly concerning because HUDs are becoming more common in automobiles, which could lead to potential roadway incursions.[25] When a particular object or event captures attention to the extent to which the beholders’ attentional capacity is completely absorbed, the resulting inattentional blindness has been known to cause dramatic accidents. Por ejemplo, an airliner crew, engrossed with a blinking console light, failed to notice the approaching ground and register hearing the danger alarm sounding before the airliner crashed.[25] Inattentional Blindness and Magic Collaborative efforts to establish links between science and magic have examined the relationship of the processes underlying inattentional blindness and the concept of misdirection—a magician’s ability to manipulate attention in order to prevent his/her audience from seeing how a trick was performed. In several misdirection studies, including Kuhn and Tatler (2005),[32] participants watch a “vanishing item” magic trick. After the initial trial, participants are shown the trick until they detect the item dropping from the magician’s hand. Most participants see the item drop on the second trial. The critical analyses involved differences in eye movements between the detected and undetected trials. These repetition trials are similar to the full-attention trial in the inattentional blindness paradigm, as both involve the detection of the unexpected event and, by detecting the unexpected event on the second trial, demonstrate that the event is readily perceivable.[33] The main difference between inattentional blindness and misdirection involves how attention is manipulated. While inattentional blindness tasks require an explicit distractor, the attentional distraction in misdirection occurs through the implicit yet systematic orchestration of attention.[34] Además, there are several varieties of misdirection and different types are likely to induce different cognitive and perceptual processes, which vary the misdirection paradigm’s resemblance to inattentional blindness.[34] Although the aims of magic differ from those of neuroscience; magicians wish to exploit cognitive weaknesses, whereas neuroscientists seek to understand the brain and the neuronal significance of cognitive functions. Several researchers have argued that neuroscientists and psychologists can learn a lot from incorporating the real world experience and knowledge of magicians into their fields of research. The techniques developed over centuries of stage magic by magicians may also be utilized by neuroscience as powerful probes of human cognition.[35] See also Attention Attention disorders Attentional Blink Memory Perception Three-Card Monte References ↑ Jump up to: 1.0 1.1 1.2 1.3 1.4 Rock, Yo., Linnet, C.
